GiroDisc two-piece floating front rotors with caliper spacers for the McLaren 570GT / 540C / MP4-12C. A direct replacement for the OE cast iron disc, 380mm in diameter against the 370 mm OEM rotor. Used with performance pads and high-temperature fluid, they address overheating and warping rotors.
Key Features
- Curved vane design, developed in racing, acts as a centrifugal pump to force cooling air through the disc
- Floating mount keeps axial and radial float between hat and disc and lets the rotor self centre between the pads
- Anti-noise spring washers allow for heat expansion and eliminate the rattle associated with floating rotors
- Once fitted, only the cast iron rotor needs replacing when worn
